Advice on selling a coin collection

[Halothane]

My father has a "coin" collection he amassed mostly during the 70's and 80's. It contains gold and silver and some novelty Franklin Mint collections (US President coins and those types of collections).

I have offered to help him sell it off slowly so he receives maximum value for what he has.

Does anyone have advice, suggestions or prior experience selling off coins and gold/ silver ingots and the like?

Should I buy a coin book of valuations? Just google each item and try to gauge condition, etc?
Where should I look to sell? eBay, coin forum/ websites?
Any and all help appreciated.

Thanks in advance.
